A student was shocked to discover a giant cornflake in his cereal which he initially thought was a piece of ''ceiling''.
Hinay Lad, 22, discovered ''rock hard choking hazard'' in his morning breakfast and was initially confused before realising there must have been a product mistake.
He told the Metro: ''It just looked like a bit of ceiling had fallen into the box.
''We were like 'what's going on here?' I thought it was a bit dangerous because it could have been a choking hazard. It felt like a rock, if you tried bending it, it wouldn't break. That's why we thought it was a bit of ceiling.''
After getting in contact with Kellogs, he was asked to send the cornflake back for testing and was given £4 worth of vouchers to buy himself a new box of cereal.
